Area code 630

Area code 630 serves Illinois, including Roselle, Hinsdale and La Grange (Central time). It has been in service since August 3, 1996 and shares its area with 331.

Numbers starting with 630 drew 1,845 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 1,407 complaints to the FCC since November 2023. The number on your screen can be faked, so a 630 number proves nothing about where a call came from.

Phone companies holding 630 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 62% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
